If you were to test the TX5 to the extreme, Sony assures us that it would be able to handle temperatures as low as -10 degrees Celsius, water depths of 3m and you can drop it from a height of 1.5m without the fear that you've just borked your brand-new camera.

Features on-board include Sony's rather marvellous Sweep Panorama mode and 10fps burst mode.

H55 is alive

Sony also announced the arrival of the H55. It may not be waterproof, but it does have some super-zooming capabilities.

Brandishing a 14.1MP sensor, the camera can zoom optically up to 10x and will stop shake due to its Active Mode feature.

Thankfully Sony has also opted to add an SD card slot to the cameras, so you can use the cards you have lying around rather than resort to the company's proprietary Memory Stick media.

If you want to use Memory Stick, though, there is an option for this too.

The new Cybershot DSC-TX5 and DSC-H55 have a UK release date of March 2010. Pricing is still to be confirmed.
